HCPL-2400 Equivalent & Substitute Parts

Part Overview

The HCPL-2400 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 3.75kV isolation rated device operates at 40MBd data rate with tri-state output configuration and 1kV/µs common mode transient immunity. The component is currently in active product status with 3025 units available in stock. Substitute parts are identified to address packaging variations and compliance requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-2400 are identified based on strict equivalence of the following critical parameters:

• Voltage isolation rating: 3750Vrms
• Common mode transient immunity: 1kV/µs minimum
• Data rate: 40MBd
• Output configuration: Tri-state logic
• Output current per channel: 25 mA
• Propagation delay specifications: 55ns maximum (both rising and falling edges)
• Supply voltage range: 4.75V to 5.25V
• Operating temperature range: -40°C to 85°C
• Package type: 8-DIP (0.300", 7.62mm)
• Mounting configuration: Through hole

The HCPL-2400-000E variant meets all electrical and mechanical requirements identical to the base HCPL-2400, with the primary difference being packaging format (tube packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-2400 and HCPL-2400-000E are active products from Broadcom Limited with identical electrical performance and mechanical compatibility. Selection between these variants depends on regulatory and compliance requirements:

• HCPL-2400: Select this variant for applications where RoHS non-compliance is acceptable or where legacy component specifications are required. Standard packaging available with 3025 units in stock.

• HCPL-2400-000E: Select this variant for applications requiring ROHS3 compliance. This part maintains all electrical and thermal specifications while meeting current environmental regulations. Tube packaging format with 6000 units in stock.

Both parts share identical isolation voltage, data rate, propagation delay, and thermal operating range. Pin configuration and PCB footprint are identical, enabling direct substitution at the board level.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2400-000E replace HCPL-2400 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The HCPL-2400-000E provides the same 3750Vrms isolation, 40MBd data rate, and tri-state output configuration. The 8-DIP through-hole package dimensions are identical, allowing direct PCB substitution.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (tube for -000E variant) and RoHS compliance status. HCPL-2400-000E meets ROHS3 requirements, while the base HCPL-2400 is RoHS non-compliant. All electrical specifications, including isolation voltage, data rate, and output current, are identical.

Q: Are there any thermal or performance differences between these variants?

A: No. Both variants operate across the identical temperature range of -40°C to 85°C with matching propagation delay specifications of 55ns maximum. Rise and fall times, forward voltage, and all other electrical parameters are identical.

Q: Which variant should I specify for new designs?

A: For new designs, specify HCPL-2400-000E to ensure compliance with current environmental regulations (ROHS3). This variant is actively produced and maintains full compatibility with existing HCPL-2400 designs.

Q: Are both parts available in the same quantities?

A: Inventory levels differ. HCPL-2400 has 3025 units in stock, while HCPL-2400-000E has 6000 units available. Both are listed as active products.
